Create DNS record for the Ingress host

The traffic on the Ingress host vault.ingress.staging.core-os.net must reach the Ingress controller in the Tectonic cluster.

To enable this, create a DNS alias record for vault.ingress.staging.core-os.net which redirects traffic to the ELB of the Tectonic cluster.

Find the DNS name of your Tectonic ELB from the AWS console. The ELB should be named <tectonic-cluster-name>-con.

Create a record set in the hosted zone for the Ingress host. This example creates the record set named vault.ingress.k8s.staging.core-os.net in the hosted zone staging.core-os.net. Choose type: A and select Alias: Yes. Set the Alias Target to the DNS name of the ELB from the previous step.

Access the Vault service through the Ingress host

The Vault CLI should now be able to successfully interact with the Vault service through the Ingress host.
